• Charge the battery as indicated in the
Charging the speaker section.
• Turn up the volume (on your speaker
or external device).
• In BT/TWS mode, make sure that
the speakers are placed within 10
metres of each other and there are
no obstructions. Check the Bluetooth
function on the external device is
on and pair the speaker(s) again if
necessary.
• In AUX IN mode, make sure that the
cable is properly connected, and the
external device is working correctly.
• Check if the audio device is A2DP-
compatible. If it is, activate the A2DP
stereo mode.
• Turn off nearby Bluetooth devices.
• Try saving the files onto a newer/
better-quality USB stick.
• Only MP3, WAV, WMA, FLAC and AMR
files can be played.
• Change to USB mode.
